Get great sound throughout the room with Logitech's Pure-Fi Express Plus Speaker Dock for your iPod or iPhone. The Pure-Fi Express Plus features omnidirectional acoustic technology, which provides great sound at a more consistent level throughout the room. It also includes the ability to run on AC or battery power, which--along with an integrated handle--makes it easy to take your music from room to room. Other features include a clock with alarm, so you can rest assured that you’ll wake on time; and a wireless remote control that works from up to 30 feet (10 meters) away, and stores neatly in an integrated compartment. In all, it's a great way to dock, play, and charge your iPod or iPhone.

Logitech’s Omnidirectional Advantage: Make Any Spot in Your Room a Sweet Spot You don't sit in one spot when you’re listening to music from your iPod. Shouldn’t your speakers produce great sound no matter where you are in your room? Most of today's speakers for the iPod are designed to deliver the highest-quality sound immediately in front of the speakers. If you move from what audiophiles call the sweet spot on the couch to the impromptu dance floor, the sound you hear can easily become distorted, and you might find yourself out of step.

The Logitech Pure-Fi Express Plus omnidirectional speakers are designed to transmit sound more consistently over a wider range of space, so you never miss a beat--no matter where you are in the room.

Traditional Versus Omnidirectional Loudspeakers Most speakers are designed to radiate sound in a fixed direction. As shown in Figure 1, traditional speakers optimize sound for a sweet spot located directly in front of the speakers. In other words, the sweet spot is limited to a constrained sound field that fans outward in one direction. If you’re outside the sweet spot, you’ll hear unbalanced sound due to loudspeaker directionality.

Logitech Audio Labs' omnidirectional speakers differ from traditional speakers. Designed to radiate sound more uniformly over a wider range of frequencies and angles, Logitech’s omnidirectional speakers create a broad sweet spot that is not dependent on a fixed listening position, as shown in Figure 2. The true hallmark of omnidirectional speakers, however, is the increased sound quality that comes from tonally balanced direct and reflected sound. The increased reverberant sound field also increases the sensation of spaciousness and listener envelopment. By designing loudspeakers to radiate sound more uniformly, Logitech delivers great sound to any spot in the room.

Omnidirectional Acoustic Technology Normal stereo desktop speakers deliver sound from discrete sound locations, making a more focused sweet spot. Logitech’s omnidirectional speakers transmit sound consistently across the room and create a much larger sweet spot, allowing for great sound anywhere in the room.
